You don't mention wath is the diameter of your dishes and if they are prime
focus dishes or offset dishes.
By the way Ku-Band or C band dishes are good for P3E but in order to designe
the type of feed it is necessary to know the dish focus /diameter i.e the
For 2400 MHz on OSCAR-13 and AO40 I have used with good results a 4"
diameter prime focus dish with a F/D ratio of 0.45 and I plan to use the
same dish for P3E
